METHOD P3 MAKING- A TGUTH BRUSH.

implication filed January 13, 1914.

known that I JOSEPH Sononrs, a su ricer of the German Emperor, and resid- "l East @ne Hundred and Sixtycity county of ilew Y New York, have invented l Improved Method of Brush, of which the folcnfication. 'eniion relates to a method of 00th brush which is so constructie bristles will straddle the teeth ii ire latter will become thoroughly at their grinding surfaces as Well as r our-er and inner sides. The brush is ized, that its component parts may dily formed and that they may be assembled in a reliable and simple manner.

in the accompanying drawing: Figure 1 from; View of the brush back before j bent; Fig. 2 a. similar View of the stool: Fig. an end View of Fig. 1; Fig. l .1 similar view of Fig. Fig. 5 a front View of the brush back and stools showing them senibled, but prior to bending; Fig. 6 an end View of the brush complete, and Fig. 7 .1 front View of the brush complete, with he handle portion partly broken away.

The brush comprises essentially a head 10 which is-niade of U shape and from which extends :1 preferably integral handle 11, the Whole constituting the stock. Head 10, is somewhat"thinner than handle 11,- and is provided on its inner oonca e face Witha pair of parallel undercut flanges 12, that extend at right angles to handle 11. These liar engage the beveled longitudinal cdg s 13 of the brush back 14, which is also of l shape and has a curvature corresponding to that of head 10. The brush heel; is provided with two opposed rows of bristles Specification 01 Letters Patent.

15, which project from both sides as Well as from the crown thereof so as to form between their Workingedges a substantially triangular opening 16 adapted to straddle a tooth. It will be seen that by manipulating the brush in the ordinary ma1mer',-the bristles will brush the front, the back and also the grinding edges of the teeth so that the latter thoroughly cleaned.

in consfiructing the brush, aluminium or other bendable material should be used for the head 10 as Well as for the back 14. The head is first perfectly straight forming a ross bar to the handle. the Whole being substantially shaped (Fig. 2). The back 14 which .is also formed of a straight strip (Fig. .1.) is slipped lengthwise into the head, so that the flanges 12 of the latter engage the beveled edges 13, andthus securely ailix the back to the head (Fig. 5). The head together with the back are then bent into the curved form desired (Fig. 6) by Which operation the back becomes permanently locked to the head against longitudinal Withdrawal thereby forming the U-shaped composite brush head.

I claim:

Method of making a tooth brush Which consists in forming av bendable T shaped stock having a flanged head, slipping a bendable bristle-carrying back into engagement with said head and simultaneously bending the head and back whereby the back becomes permanently locked to the head to form a composite U-shaped brush head.
